What is it?

The E2R16v2 adapter adds support for the ROM pinout compatible EPROM of the 27C400/800/160 and C322 series to the common MiniPro TL866 programmer. Bare PCB or SMT option. Requires assembly.

What is included with the SMT option?

All SMT components are preassembled on the board. Only 4 parts are required to complete the project: 2pcs 20-pin header 1pc 8-pin dip switch 1pc 48-pin ZIF zocket

What is included with the Kit option?

One black PCB with all the SMT component preassembled plus the 4 parts above. Still requires soldering.

Why did you make it?

The Minipro TL866 is very popular among hobbyist because of its low price and ease of use. Its list of supported chips is however somewhat limited compared to more expensive professional programmers.

Quick Start

To use the adapter to read or write 27Cxxx EPROMs select 27c4096 and de-select "check ID" in the Minipro GUI. Set the DIP siwtch according to the 512KB bank that need to be read/written. Additionally, for programming make sure the section "IC Config Information" is set according to the datasheet of the specific EPROM being programmed. Then read and write as usual. Repeat for every 512KB bank.
